The Role

T1 Energy is looking to hire an experienced Cost Accountant to be based at our Austin, TX HQ with occasional travel to our facility in Wilmer, TX. This is a hands-on, critical role for someone who thrives on the plant floor as much as they do in the numbers, managing and improving manufacturing cost accounting processes, strengthening financial controls, and helping drive a faster, more efficient monthly close.

You'll work closely with plant operations, supply chain, and corporate finance, while also serving as a key finance partner to the GM for ad hoc accounting and financial analysis. If you're a proactive, process-minded accountant who loves the complexity of manufacturing cost structures and isn't afraid to roll up your sleeves and build something better, this role is for you.

What You'll Do

Cost Accounting & Inventory

• Maintain and analyze product and manufacturing costs, including materials, labor, overhead, and variances.

• Perform standard cost maintenance, cost roll-ups, and variance analysis within Oracle.

• Partner with operations and supply chain to understand cost drivers and improve cost visibility across the plant.

• Own inventory accounting for raw materials, work in process (WIP), and finished goods at the plant level.

• Ensure accurate inventory valuation in accordance with GAAP, including standard costing, inventory reserves, and period-end adjustments.

• Support cycle counts and physical inventories, including planning, reconciliation, variance investigation, and adjustment documentation.

• Analyze inventory variances — usage, yield, scrap, and obsolescence — and partner with operations to drive root cause resolution.

• Ensure accurate and timely recording of manufacturing transactions.

Month-End Close & Reporting

• Support and continuously improve the month-end close process with a focus on speed, accuracy, and transparency.

• Prepare and review cost-related journal entries, reconciliations, and supporting schedules.

• Assist in management reporting related to plant performance, margins, and operational KPIs.

Process Improvement & Best Practices

• Help establish and document cost accounting best practices in a growing manufacturing environment.

• Identify and implement process improvements to streamline accounting workflows and strengthen controls.

• Support system and process enhancements related to Oracle and manufacturing finance.

Plant & General Manager Support

• Serve as a finance partner to the Plant General Manager on ad hoc accounting, financial analysis, and business questions.

• Provide financial insights to support operational decision-making at the plant level.

• Assist with special projects related to continuous improvement initiatives.

Who You Are

• Technically sharp and grounded in GAAP — you know the rules and know when something isn't right.

• Detail-driven without losing sight of the bigger picture and what the numbers mean for the business.

• Structured, organized, and disciplined in execution, especially when the close is bearing down.

• A clear communicator who can translate financial results into insights that operations leaders can actually act on.

• Calm and effective in fast-paced, evolving environments — manufacturing moves fast and you move with it.

• Comfortable working cross-functionally with operations, supply chain, and leadership at all levels.

• A continuous improvement thinker who sees every manual process as an opportunity.

Qualifications

• Bachelor's degree in Accounting or Finance; CPA preferred.

• 5+ years of relevant experience in cost accounting within a manufacturing environment.

• Hands-on experience with Oracle, specifically costing, inventory, and general ledger modules.

• Strong understanding of manufacturing cost structures and variance analysis.

• Ability to work effectively on-site in a fast-paced plant environment.

• Strong process documentation and SOP development experience.
